SPECIFICATION forming part of Letters Patent No. 269,980, dated January 2, 1883.

Application filedJuly 28, 1882. (No model.)

To all whom it may concern: 7

Be it known that I, DAVID WOLF, of Avon, in the county of Lebanon and State of Penn sylvauia, have invented certain new and usetel Improvements in Horse-Powers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in horse-powers, the object of the same being to provide positive means for transmitting power from the master-wheel to the main drivingshaft, which latter is situated on the under side of the masterwheel at two points, and thereby lessen the strain on the several parts, and consequently cause the machine to run much more smoothly than those ordinarily employed; and with these ends in view my invention consists in the parts and combinations of parts as wili be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1. is a plan view of my improved device with the master-wheel removed, and Fig. 2 is a" side view with the master-wheel in position.

A represents the master-wheel, made of cast metal, and provided on its lower surface with teeth, by means of which motion is transmitted to the driving-shaft. 'This wheel A is pro vided with a central hub, B, from which the arms 0 radiate, and the said hub is provided with as many sockets or recesses a as there are levers D. These levers D rest on and are secured to the arms 0, and the ends thereof .enter the sockets a, which, together with the screws which secure the levers to the arms, hold the said levers firmly in position. The arms 0 incline upward from the hub B, and are securedat their outer ends to the masterwheel A by the downward extensions 1) of the said arms. The master-wheel A is journaled on the pivot-bolt E, which latter is rigidly secured to the transverse bar F. This bar F is rigidly secured to the base G by the hook-bolts H, the hooked lower ends of which pass under the curved base G, while the shanks thereof pass upward through the guide-blocks I and are secured in position by nuts. The guide blocks(two in number) are situated on opposite sides of the machine, and each one is provided with an overlapping lip, c, which, to

gether with guide-rollers, to be hereinafter described, hold the master-wheel down in engagement with the smaller cogs, which latter are situated under the said master-wheel in close proximity thereto.

The lower bearing-face, d, of the bearingblocks I extend laterally'from both sides of The base G is curved, as shown in the draw ings, and is provided on one side with the single bearing J, in which one end of the main driving-shaft K is journaled, and on the opposite or straight side with the double bearings, in which the opposite end of the main shaft and the supplemental cog are journaled. This main shaft runs transversely between the master-wheel and the base, and is provided with two cog-wheels, L and L, one of which is so situated as to mesh with the master-wheel, while the opposite one is situated in a lower horizontal plane than the master, and consequently does not engage'therewith. This difference in the level of the two wheels, which are of the same size, is caused by placing the main driving-shaft in an inclined plane instead of in a horizontal one. This cog-wheel L is rigidly secured to the main driving-shaftand gears with the master-wheel, while the wheel L is also rigidly secured to the said main shaft, but gears with the supplemental wheel N. This wheel N is slightly larger than the wheel L, and is journaled in the double bearing alongside of the wheel L and meshes with. the master-wheel A. A single cap-piece, 0, covers this double bearing and holds both wheels down in position.

Brackets f are secured to the cap-piece on the single and double bearings, and are each provided with a friction roller, g, which bear on the top of the master-wheel and assist in holding it down in position. I

The horses are secured to the levers D in the ordinary manner, and as the master-wheel is revolved it meshes with the wheel L and revolves the main shaft. This would be sufficient to turn the said shaft, even if it were operating machines from both ends; but all t strain from the "parts would fall directly on this wheel and the portion of the master-wheel immediately in contact with the wheel L, and would consequently create a great amount of friction and cause undue wear of the parts and strain on the driving-shaft, and to overcome these objections I connect the main shaft to the opposite sides of the master-wheel, which distributes the strain and wear evenly to all the parts. As the master-wheel revolves it turns the wheel L on the main shaft, and also the supplemental wheel N, which engages the wheel L on the main shaft, and assists in operating the machines to which the horse-power is connected. Heretofore this has been actwo gear-wheels, and passing the shaft in an inclined or oblique direction through the maswith the bottom or lower side thereof.

ter-wheel, so that one gear would mesh with the top of the said master-wheel and the other This is objectionable for the reason that it is expensive, cumbersome, and is liable to get out of repair.

My improvement is simple in construction, is of few parts, and consequently can be manufactured at a small cost. 7 It is adapted to drive two grain-thrashing or similar machines at the same time; but when it is only necessary to run one machine it can be accomplished without straining the parts.

It is evident that slight changes in the construction and relative arrangement of parts might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do notlimit myselfto the exact construction shown and described,

but consider myself at liberty to make such changes as come within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a horse-power, the combination, with the master-wheel, of the main shaftjournaled below the master-wheel and provided with two cogwheels rigidly secured thereto, one of which engages the master-wheel, while the other engages indirectly therewith through the intervention of a supplemental cog-wheel, substantially as described.

2. In a horse-power, the combination,with the base of the machine, the transverse bar, the guide-blocks, and the master-wheel, of the main shaft provided with acog-wheel rigidly secured thereto, which engages directlywith the master-wheel, a second cog-wheel rigidly secured to the said shaft, and a supplemental wheel situated alongside this second cog-wheel, and indirectly connecting it with the masterwheel, substantially as described.

3. In a horse-power, the combination, with the base, transverse bar, the masterwheel provided with a socketed hub and inclined arms, the draft-levers, and suitable guide- 6 blocks, of the incllned main shaft, two cogs secured thereto, and a supplemental cog connecting one of the cogs on the main shaft with the master-wheel, substantially as described.

4. In a horse-power, the combination, with the base, curved as shown, and provided on one side with a single bearing, on the oppo-' site side with double bearings, the transverse bar, and the master-wheel, of the inclined driviug-shaftjournaled inthe base and provided with a cog-wheel adapted to engage directly with the master-wheel, a second cog-wheel secured thereto, a supplemental cog-wheeljournaled in the double bearing alongside of the driving-shaft, and adapted to indirectly conuect the last-mentioned cog with the masterwheel, ancl'the guide-blocks and rollers, all of the above parts constructed, combined, and adapted to operate as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

DAVID WOLF.
